f6d48b618a avcodec/mediacodec: add av_mediacodec_render_buffer_at_time() 
The existing av_mediacodec_release_buffer allows the user to render
or discard the Surface-backed frame. This new method allows the user
to control exactly when the frame will be rendered to its SurfaceView.

Available since Android API 21.

8f15248024 avcodec/aacdec_template: Allow duplicated elements 
Such streams are invalid according to

...cIn the raw_data_block(), several instances of the
same syntactic element may occur, but must have a different 4 bit
element_instance_tag, except for data_stream_element()'s and
fill_element()'s.

b1504e7796 h264_slice: Copy the value of x264_build before calling h264_slice_header_init during thread init 
If we don't copy this value first, it is seen as 0 by h264_slice_header_init,
due to zero-allocation of the new context, triggering an old hack that
multiplied the denominator by 2 for files produced by old x264 versions, but
only if more than one thread was used.

Fixes #7475 and #7083.
